我在互联网上找到了这个代码，我修改了它供我使用，我不确定我在这里做错了什么，我收到这个错误卷曲错误：SSL 连接超时登录部分成功，但搜索对我不起作用。有人可以帮我吗？

尝试添加这个（但不要在生产中设置此选项！
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
如果它之后工作，那是因为 CURL 无法协商 SSL 证书。
按照本教程了解如何获取 CA 证书的步骤：http://unitstep.net/blog/2009/05/05/using-curl-in-php-to-access-https-ssltls-protected-sites/
其他需要研究的是，在 curl_exec（） 之前，curl_copy_handle();然后设置其他参数。
此外，或者，您可以使用 curl_init($url); 重新启动 cURL。
使用我列出的 2 个选项暂时禁用 SSL 验证，可能就是这样（如果证书设置不正确）。 请注意"CURLOPT_SSL_VERIFYHOST"选项。 否则我只会更多地玩这些选项。 此外，您不必遍历这些值，只需使用关联数组即可。
<?php
//create array of data to be posted
$post_data['username'] = 'user';
$post_data['password'] = 'log';
$post_data['cmd'] = 'log';
//create cURL connection
$curl_connection = curl_init();
//set options
curl_setopt($curl_connection,CURLOPT_SSL_VERIFYHOST,0);
curl_setopt($curl_connection,CURLOPT_SSL_VERIFYPEER, false);
/...
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_data);//it can accept associative arrays
/...
?>
尝试其他答案后，我仍然收到SSL connection timeout错误。
我检查了我的php.ini，并决定检查是否有任何与OpenSSL相关的内容，我确实发现：
;extension=php_openssl.dll
我通过取消注释该行来启用它。
extension=php_openssl.dll
现在，启用OpenSSL（这是Windows上的参数，在Linux/Mac上应该类似），重新启动我的Apache服务器后，我终于可以执行我的cURL请求而没有任何错误了！
